What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This early-phase trial tests a new drug called PRL3-zumab in 15 people with wet age-related macular degeneration (nAMD) who have not improved with standard treatments. The drug is given by IV every two weeks for three doses. The study will check for safety and any signs that vision or eye health may improve.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
PRL3-zumab (a lab-made antibody given by IV)
What this could lead to
If it works, this could offer a new treatment option for people with wet AMD who have not responded to current therapies.
What could go wrong
This is a very early, small study (15 people) focused on safety. It may not improve vision, and side effects are unknown. Success in this small group does not guarantee broader benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients with Neovascular Age-related Macular Degeneration (nAMD). 2. Willing to provide written informed consent for the study. 3. Patients undergoing intravitreal treatment having failed at least two Standard-of care treatments and be receiving ongoing intravitreal treatment at intervals of ≤ 8 weeks including Ranibizumab, Aflibercept, or Faricimab. 4. Participants receiving intravitreal treatment at screening must complete a wash-out period before enrolment. This wash-out period should be calculated based on five half-lives of the specific intravitreal treatment the participant is receiving. Below is the washing out period for some standard of care treatments. 1. Ranibizumab (half-life: 9 days) requires a wash-out period of 45 days (7 weeks) 2. Aflibercept (half-life: 11 days) requires a wash-out period of 55 days (8 weeks) 3. Faricimab (half-life: 7.5 days) requires a wash-out period of 37.5 days (5 weeks) 4. Bevacizumab (half-life: 6 days) requires a wash-out period of 30 days (4weeks) 5. Subfoveal CNV or juxtafoveal/extrafoveal CNV with a subfoveal component related to the CNV activity identified by FFA or OCT (where CNV activity is defined as showing evidence of subretinal fluid, subretinal hyperreflective material, or leakage). 6. BCVA ETDRS letter score of 78 to 24 (corresponding to a Snellen equivalent of approximately 20/32 to 20/320) in the study eye. 7. Decrease in BCVA determined to be primarily the result of nAMD or DR/DME in the study eye. 8. Presence of pigment epithelium detachment (PED), intraretinal fluid (IRF) and/or subretinal fluid (SRF) affecting the central subfield of the study eye on OCT. 9. Adequate organ (liver and renal) and hematological functions as evidenced by the laboratory results obtained within 7 days of treatment which are within the normal range for the study population, or with abnormalities deemed not clinically significant by the investigators. Exclusion Criteria: 1. Scar, fibrosis, atrophy, or retinal pigment epithelial tears involving the central fovea in the study eye. 2. Uncontrolled glaucoma (defined as IOP \>25 mmHg despite treatment with antiglaucoma medication) in the study eye. 3. History of idiopathic or autoimmune uveitis in the study eye. 4. Myopia of a spherical equivalent of at least 8 diopters in the study eye prior to any refractive or cataract surgery. 5. Evidence of extraocular or periocular infection or inflammation (including infectious blepharitis, keratitis, scleritis, or conjunctivitis) in either eye at the time of screening/randomization. 6. Uncontrolled blood pressure (defined as systolic \>160 mmHg or diastolic \>95 mmHg). 7. Patient is receiving systemic glucocorticoids (only if higher than 10mg or equivalent of prednisolone daily) or other immunosuppressive treatment for autoimmune disease or any other medical condition.
